EDIT: Minor update.
EDIT 2: 1 year andd........
I am just gonna put it here from my note before I lose it. I base this on Aveyond 2 and 3.
Kingdoms of Aia....
Mainland:
Thais
Harburg
Stormbend
Quinn/Istir
Naylith
Gheledon
Orc Empire
Underwold
Aveyond
Witchwood (the old one like we see in AP, swallowed in the swamp)
Bogwood (renaming it to Witchwood and also cursed the land into mystic forest like in AV3)
Shaenlir (possibly shifted away from the Mainland. I still consider Quinn and Shaenlir are not the same kingdom even though both lies North West of Thais)
Candar (possibly shifted away from the Mainland.)
Isles:
Tar Vedron
Dragkthor
Venwood
Faiara
Verashema
Eredar
Storybook
Eldrion:
Peliad
Harakauna (Animalville)
Tyobi (In my theory, it was once called Seri but shifted away from the Mainland. Another wealthy family inherited the throne hence giving it a new name.)
Seri (Headcanon: The bloodline still continues after a new bloodline takes over Seri and renamed it Tyobi. The location is quite distant to Tyobi.)
Shoal Leui
Acropolis (the unknown kingdom)
Underfall
Arishta Isles:
Veldarah
Sedona
Veldt (somehow shifted away from the isles before the mountain ranges formed - too bad that it is retcon but that's only a legend :p)
Northern Kingdom (least populated kingdom)
Mysten Far (possibly the closest ally to Aveyond)
The Vale: (once part of Arishta Isles but somehow magically transported)
Oldwoods
Ylisfar (underground just like in AV1)
AV4: (faraway from the Mainland)
Wyrmwood
Halaina
Ravwyn
Delamare
Var'thor
Mist Realm
Ulrock
Weeville
That's it 😃
Unmentioned Towns:
Devenshire, Thais
Elden, Harburg
Glenvale, Quinn
Ryva, Thais
Ravenwood, Thais
Happily Ever After, Storybook
Casket Hill, Underworld
Ghed'arhe, Underworld
Clearwater, Sedona
Brumwich, Sedona
Dirkon, Sedona
Veniara, Veldt
Ghalarah, Veldarah
Windshire, Halaina
Tor, Halaina
Bazaar, Venwood

I replayed Aveyond partially on Christmas week and it got me interested on the world of Aia and its kingdom. Right know, I am connecting the dots between how this land conjoins this land and etc.
Though I have limited time because I'm busy, I am actually finding the world maps from AP to Aveyond 4. Spare?😁
And for the kingdoms, I probably research them in google and list them down.

Review isn't my thing but I think I feel that my opinion on this game needs to be express.
Characters [7/10]
A new cast of rather intriguing personalities. We have Boyle who thought of becoming a hero is inferior, Myst- a snarky wanna be fun-loving character perhaps my favorite as well and so forth. I could explain everyone on the cast but that's not my cup of tea. Special mention for Hi'beru and Rowen also the party interaction is something near fun.
Overall the cast is a hybrid of fun like Aveyond I, and overwhelming. Why overwhelming?- personal taste is too opinionated for me but some characters tries too hard to execute impression, I won't give names.
Music [8.5/10]
The music isn't a 9 worthy or 8 worthy, something in between is satisfaction.
My favourite soundtrack is Halaina- I just love the medieval feels when I am hearing it while ambling around the town. Also, Halaina is near Byzantium or Venice when it comes to details.
The music for this games is soothing. That's it, ran out of words this time.
Gameplay [5/10]
Not a fan of the footsteps, incredibly irritating, and the back-and-forth situation.
The enemies seems repetitive, sorry if I'm being mean-spirited, and kinda gets boring after a while (Goblin here, goblin there) tho there is some positive effects of this like not having weird creatures out on a forest.
The menu screen is alright, seems John Wizard-y for me.
The battle? Good overall, everyone in the cast is begotten though their own ways.
Art [4/10]
Monotonous. Doesn't really wowed me unlike Aveond III plus it kinda looses the charm of an Aveyond game.
Story [7.5]
A villain tending to be a hero? This seems fun. Not much to say about this. I'm not really vocal like the pessimistic impatient critiques, I try to be optimistic as I can.
Of course we have Myst to continue the plot, LOL
Overall: 6/10~above average while maintaining its quality.
"How to be social?" - Hi'beru

After replaying some forgettable Aveyond games earlier this year... I feel like all stories are light weighted and have a decent amount character development throughout the gameplay but it doesn't mean I don't like the games at all, I'm just nitpicking.
